There are lots of things that can cause cooling problems. One of the most common causes of poor cooling in a frost free refrigerator is a defrost system failure... Compressor Running But Not Cooling: in such a case one or the other compartment may appear to be keeping proper temperature but that too may change in a short period of time. The fridge compartment's temperature rise is usually (but not always) the first to be noticed.

Note: The compressor should usually be running whenever any of the fans (evaporator fan in the freezer and condenser fan by the compressor) are running. All should run together while the refrigerator is in cooling mode.

The refrigeration system's evaporator (cooling) coil is usually in the freezer compartment. This evaporator will periodically frost over and have to be defrosted by means of a heating system. When the defrost heating system fails, the frost can accumulate to such a degree that airflow throughout the appliance is hampered. There may be just enough air circulation to cool the freezer section but that will eventually stop too.

Defrost timers frequently fail and stop keeping time. If this happens during the cooling mode, it will allow excessive frost to accumulate on the cooling coil reducing air flow, eventually stopping it altogether as it never switches into defrost mode to melt it. The timer can also stick in the defrost mode and never advance into the cooling cycle again.

Need additional details to diagnoticated; there are a few reasons why the refrigerator part will not cool...here are a couple of tips that will help you to figure out why the refrigerantor is not cooling:
* Refrigerator not Cooling or Fridge not Cooling
* How to Defrost Refrigerator Defrost Timer Problem

1.
Read and follow this to find out the problem :


First if all empty the drain pan .

Defrost can be the cause for your refrigerator not cooling problem. To check to see if you have a defrost problem, look in the freezer to see if there is ice build up on the evaporator cover. (The evaporator covers are either in the back of the freezer or on the bottom of the freezer).
2.
Fans not running will cause the fresh food and the freezer sections not to work. If the condenser fan (the one under refrigerator) is not working, the compressor will cut off on the overload. If the evaporator fan is not running, there will be no airflow to the freezer or the refrigerator. First walk up to the refrigerator and listen to see if the fans (one in the freezer on one under the bottom) are running. If one is running and the other is not then get to the one that is not running and see if something is blocking it. If there is nothing blocking it then replace it. (Note that some refrigerators cut off the fan inside the freezer when you open the door so be sure that the door switch is depressed when performing this test).
3.
On a top-freezer when the drain stops up water will back up turning to ice and eventually filling the air ducks with ice blocking airflow to the fresh food section causing it not to cool. You will also see a water leak inside the fresh food section. To fix this, remove the evaporator cover, (back or bottom of freezer) and then remove all the ice. Once all the ice is removed, you need to unclog the drain. I do this by forcing hot water down the drain with a turkey baser but you can use any squirt bottle, I have even used the water hose. Once the drain is clear, mix water and baking soda and pour it down the drain to prevent this from happening again anytime soon.
4.
Dirty condenser can be the cause for your refrigerator not cooling problem.. If the condenser is dirty, the compressor will cut off on the overload. (A thermostat that is on the side of the compressor that cuts it off if it overheats). Often when this happens you'll hear a clicking noise about 2 to 3 minutes apart. This is your compressor cutting in and out as it overheats and cools off. Now you need to find out why the compressor is overheating. First you're going to need to remove the cover from the back of the refrigerator. Once you remove the cover you should see the compressor. Now look at the condensing coils (condensing coils are going to be either behind the compressor, beside the compressor or on the back of the refrigerator) to see if they are dirty if so clean them. To clean the condenser I normally use a brush made for this. You can buy them at Wal-Mart. Once clean your problem may be fixed. Leave refrigerator unplugged for a while (20 min. or so). Then plug it back in and if the compressor doesn't overheat problem is fixed. If it still overheats read on.
5.
The start relay can also cause the fresh food and the freezer sections not to work. If the start relay is bad, the compressor will not start and you will hear a clicking noise in 2-5 minute intervals. The clicking noise is the overload cutting the compressor off when it overheats from trying to start with a bad start relay. To find out if this is bad first unplug the refrigerator. Then take the cover off that is on the side of the compressor. Now you should be able to see the start relay plugged on to the side of the compressor and unplug it. Now the best way to tell if it's bad is to shake it. If it rattles, it's bad and needs to be replaced. If not, most of the time it's ok. But rather than saying the compressors bad, you might want to replace it anyways because it don't cost much in most cases (less than $25). If you replace it and it doesn't work then the compressor is bad and you'll need you call a repairman. (Note that compressors are very costly and are normally not worth fixing).
6.
If your refrigerator is stuck in defrost, this can be the cause for your refrigerator not cooling problem. Just simply turn the defrost timer a ¼ turn. Defrost timers are normally located in the fresh food section near the controls or at bottom behind kick plate. If the refrigerator comes on replace timer. If your refrigerator is newer, the timer may be electronic; therefore, you can't do this. But it can still be your problem, although I haven't seen this often.
7.
The cold control can be the cause for your refrigerator not cooling problem. This is the least likely of all the problems but happens sometimes. Turn the control up all the way and tap on it. If the refrigerator comes on then replace cold control. If it still doesn't come on, it may still be bad. You can check it by first unplugging the refrigerator and taking the control out and test it with an. ohmmeter Unplug the wires and see if you have continuity between the terminals, if not replace control.
8.
Some newer refrigerators have a main control board and this can be the cause for your refrigerator not cooling problem. This can be hard to diagnose if you don't have a wiring diagram or don't know how read one. I can't help you because I would need a wiring diagram of your refrigerator to diagnose a main board

Fridge not cold enough, freezer is. How to get the fridge colder?


If there is still ice in the freezer it will need to be completely defrosted for air to circulate through the coils. Make sure the fan is turning in the right direction. a generic fan motor may not be turning in the right direction and will need to be reversed by turning the armature around if this is possible with the replacement motor most universal motors are reversable and should show you how in the directions.

The evaporator fan motor will run only when the compressor is running. If the temperature is too warm in the refrigerator, there may be something blocking the opening from the freezer to the refrigerator.

Lg lfx25960st not cool enough


1. What are your controls (freezer & refer) set at?
LG recommends 0 deg for the freezer & 37 deg for the refer.

2. The way a modern refrigerator works is, the freezer is cooled directly and cold air then is blown into the refer section. The incoming vents in a French door LG are at the back, top. Return are at the bottom. Make certain that nothing is blocking these vents and than the refer has good air circulation.

3. Vacuum the coils at the back of the refer. A large build up of dust, dirt, animal hair etc. will affect efficiency.

The refrigerator and freezer is not cooling


Few things to check:

1) Remove dirt / dust that has accumulated on the condenser coil located on the back of the fridge, or underneath. Use a vacuum to clean off with.

2) Remove dirt / dust in / around compressor area. Make sure you turn power off first as there are several areas in this area that can "bite."

3) Look for heavy frost / ice buildup in the freezer compartment. Defrost if necessary.

4) Make sure the fan is blowing in the freezer compartment.

5) Make sure there is air flow from the vent at the top of the refrigerator compartment. This air is driven by the fan in the freezer (most models).

6) Loading a lot of unfrozen food into the freezer compartment will have the appearance of the fridge going out, but is actually functioning normally as it removes heat from the food so it will freeze.

7) Your thermostat is not working correctly. Move it to the coldest setting if not already done so. Listen for the compressor to kick on. If it doesn't, bad t-stat.

Fridge not cold enough to hold milk resulting in the milk becoming sour. Fridge temperature is 10 degrees C how can we make it cooler? We have already set the temperature to the dial 7.


You could do the simple things like clean the dust and stuff around the compressor condenser. Check the condenser motor. Good air flow improves performance and cost nothing to fix. Of course if you are experiencing a defrost problem the air from below gets choke out with ice buildup around the evaporator area. If you have frost on the backside of the freezer section changes is you have a broken defrost heater.

I have a roper model RT14ZKXDWOO and the freezer is working fine but the refrig is warm. I took the panel off the back of the freezer and it is full of ice. What should i do next? and is there a diagram...


Hi,maybe I can shed a little light.I don`t know where the defrost timer is,but I would melt the ice with a hair dryer and real warm water(it will make a mess so be ready).There will be a drain inside of the freezer compartment,on the inside.Some how the rear panel inside the freezer compartment comes out.You may have to take apart the whole inside of the freezer compartment just to remove this rear panel.But when you do look for ice build up on bottom of freezing unit,and the rearof the freezer compartment.Melt this ice the same way earlier described.You will find a drain that starts inside the bottom-rear of the freezer compartment.This drain goes all the way down to the bottom of the fridge.You will find a very shallow drip pan under the fridge.This pan will most of the time only receive a little amount of water at a time and evaporates quickly.Now while you thaw this drain,water will start draining threw the drain,if it is not stoped up with food particles and such.This would be a good tome to blow threw this ine from the bottom where it drains into the pan underneth the fridge.Then blow threw it at the top in the freezer compartment.You can use a air tank with a blow gun.Be sure to pour water threw and down this drain to wash out all particles left behind.Clean the freezer compartment out good(the particles of food and such) and reassemble the freezing unit.plug fridge back up and set the freezer control to a respectfull setting(not the coldest and not real cold)and set the frideration to a decent setting for food preservation. Let the fridge and freezer run 12 to 24 hours to see if your problem comes back,and then time will tell if your defrost timer is bad,or is working like it should.When the drain clogs,it starts freezing away from the defrost elements and continues freezing the blocked water untill it overtakes the coils .The defrost and the timer don`t stay on long enough,or hot enough to overcome the ice.This is the reason you should try this solution first.If I can help you anymore,let me know roniecon@gmail.com /let me know how it turns out

Cold freezer/warm refrigerator


Same problem with Frigidaire Gallery model#GLRT182SAW5 (dated 2002 on back of case)

Vents were blocked with ice. Vents (from top compartment to lower) located behind light. You can check by poking a chopstick up the (2) holes; be careful not to hit fan blades.

Solution:

- took freezer coil cover off in back; checked that defrost heater element was working (marked and rotated the timer in the hole next to light); checked that fan working. Found ice in the vents and defrost drip area. Got it out with hair dryer.

- cleaned compressor coils in back (check fan is rotating; also tweaked some of the compressor tubing bends to make them more smooth - read somewhere about a manufacturing defect ...); blew out drip tube from defroster while down there.

- Set the freezer control to WARM and the refrig control to COLD (THIS SHOULD IMPROVE AIR FLOW FROM TOP TO BOTTOM).

- Put thermometers in top and bottom. Checked that refrigerator cycles (not running continuously). Checked that cold air is coming down from (2) vents behind light.

OK: so far, so good. Lower compartment is 40 or under. Top is under 18.

CONCLUSION: Suspect marginal design. Had problems with another similar model where defroster ice doesn't drain correctly, pools and refreezes. Leading to blocked vents as well as blocked defroster drain and similar problem including dripping water from top to bottom and warm bottom.

MAYBE KEEPING THE FREEZER CONTROL AT WARM GETS AROUND THE PROBLEM?? ANYWAY, ITS WORKING FOR ME FOR NOW !!
